>>7I'm not sure what to say now. Nearly speechless. But no, I mean, it's not abnormal to act like this. There're times when people get confused and they also make their friends & advisors get confused, too. That's just the way things usually go...
Asian girls're so troublesome. Not any harsh meaning,really, but it's true. And if you want to know, I'm Asian, too. However, it doesn't mean I could be any more useful to your matter. Still, I'll try my best in helping!
Anyway, I don't think you could pick either of those two boys yet. Just not yet, not now. And you still have to respond to boy B's confession, right? So, why don't you text him, or maybe meet him in person to tell about your true feelings. I mean, before you got a confession, you liked boy A and never thought of having any feelings towards B, is that correct? And then, when you knew your best friend's secret, everything changed as you started to care more about B.
In other words, the problem comes from boy B's confession. You got confused because of your best friend's confession. That's the problem you need to solve!
It's the best you should tell B the whole truth that you're not sure whether you liked him or not, that you'd never thought of him in such way before, ect. Just give him the real truth. And, B will surely understand. After all, he's your best friend, isn't he?
This is the best solution I can come up with. Forgive me if it's too lame...
